Abstract
The hydraulic conductivity of peat, sand and their mixtures has been investigated, using TDR and instantaneous profile methods (IPM). It was stated that the hydraulic conductivity of peat-sand mixtures depends to a large extent on the relation between their organic and mineral parts and is affected both by the soil system's structure and texture. The saturated hydraulic conductivity of peat-sand mixtures decreases if the sand part content is higher than 20%. The addition of more than 20% of sand to the peat sedge leads to a deterioration of hydraulic conductivity of sedge peat in the saturated zone.
